What are the merits and demerits of friction?
Dear student,
Merits of friction:
1: Friction allows use to write on the paper or whiteboard.
2: It allows us to walk on ground. Due to less friction, it is difficult to walk on slippery surfaces like ice.
3: Asteroids are burnt due to friction and do not reach the earth. So friction protects us from asteriods.
4: Application of brakes while driving is possible due to friction.
Demerits of friction:
1: Friction causes wear and tear of parts of machines. It damages shoe soles with time as there is friction between shoe soles and ground on which we walk.
2: Presence of friction poses need of application of extra power to make machines to perform their function.
3: Forest fires are caused by friction between tree branches and damages valuable plant and animal species.
Regards.
